The acquisition, subject to regulatory approvals, will add over 490 employees, including 315 loan underwriters spread across five centres in the United States, to Wipro's headcount, the company said in a statement on Monday.

Opus offers operational and loan-level due diligence, valuation support, forensic analysis, and advisory services for all classes of mortgage products. Its customers include several top global banks and mortgage companies, the Azim Premji-led company said on Monday.

The deal is expected to close in the January-March quarter, it said.

Wipro's profit for the July-September quarter beat analyst estimates, but lagged revenue growth of its local peers such as sector leader Tata Consultancy Services, which garner a larger proportion of their revenues from financial clients.
